Hi All,

We are using IMX8QM and facing issue in uboot to configure GPIO4_25 signal to default pulled down. Below is a

GPIO signal connected peripheral and want this signal default to pulled down in IMX uboot.

1. SC_P_QSPI1A_DATA1_LSIO_GPIO4_IO25

 

We have done changes in board_gpio_init function(board/freescale/imx8qm_mek/imx8qm_mek.c file) but the signal is still high.

But we need default GPIO4_25 signal configure low.

What is the default GPIO4_25 signal configurations?

How I can configure above GPIO4_25 signals default pulled down.

 

Please provide inputs to resolve this issue.

 

Thanks,
